Specification of Letters' Patent.

Patented Oct. 15,1912.`

Application filed July 6, 191,1A Serial No. 637,099.

To all whom t may concern:

Be it known that l, ARTHUR E. Boron, a citizen of the United States, residing at Monterey, in the county of Monterey and State of California, have invented certain new and useful mprovements in Brick- Kilns; andv I do declare the following to be a full, clear, and exact description of the invention, such as will enable othersI skilled in the art to which i-t appertains to make and use the same.

This invention relates to improvements in kilns for burning bricks and other clay products, the apparatus being known as continuous burning kilns. f

The principal object of the linvention is to construct a kiln by means of which the bricks may be gradually heated to the maximum temperature required for their burning during their manufacture and gradual cooling without cracking or checking.

Another object is to provide devices which will utilize the maximum of heat contained in the fuel used and eliminate a large pel'- 'centage of labor which is at present required in handling' and reliandling the brick dur-A ing the burning process.

Another object is to provide means for controlling at all times the heat used vin the kiln and for uniformly distributing it to all parts of the bricks being kilned and keeping the bricks under observation during the process.

Another object is to provide means for drawing oli' the heat exuding from the Cooling bricks and to utilize it for dryingrbricks made by the, several mud processes or ot such composition which require drying before being kilned.

Another object is to construct an appafratus in which the bricksI are constantly retained on the cars from the time they leave the molds unt-il the entire drying and burningprocesses are completed.

`With these and other objects in view the invention consists of certain novel features ofeonstruction. combination and arrangement of parts as will he more fully described and particularly pointed out in the appended claim` f ln the accompanyingr drawings: Figure l is a longitudinal vertical section of one end of this improved apparatus: F ig. 2 is a similar vieu of the other end; Fig. J is a` horizontal section taken through the portion of the apparatus shown in' Fig. l; Fig.

4 is a similar view taken through the portion of the apparat-us shown in Fig. 2; Fic. 5 is a vertical transverse section taken on 'the line,'5--5 of Fig. 1; Fig. (i is a similar ti'ew Itaken on the Vline 6 6 of Fig. 2; Fig. 7 is ajhorizontal section of the carrying car taken on the line 7? of Fig. 6; Fig. 8 is a vertical longitudinal section taken on the line 8-8 of Fig. 5 showing the verticalarrangement of the air passages.

In the embodiment illustrated twoparallol laterally spaced chambers or tunnels v1 and 2 are shown constructed of any suitable tire resisting material preferably of a composition of concrete and fire-brick. These tunnels may be of any desired `length and size to accommodate any desiredj'number of cars and a transfer chamber 3 is arranged transversely across one end and communicates with both of said tunnels and in which ears from one tunnel are transferred to the other tunnel as will be hereinafter more fully described. These tunnels are provided with tracks as 4 on which the cars travel, said tracks being preferably mounted on a cement 0r other suitable foundation preferably constructed of supporting beams 5 and G having an air space 7 arranged between them lto permit the passage of cool air below the cars.

The bricks from the molds are loaded onto {l'at cars preferably constructed as shown with a tire clay composition 8 arranged over the top of each car to protect the ear from the heat in the kiln dluing its passage therethrough and vertically spaced above this fire resistingplatform or cover 8 is u horizontally disposed table or platform 9 composed of fire resisting material and having a multiplicity of openings as 10 therein to permit the passage of the heated air from the bricks supported thereon to the space or chamber formed between said platform and the upper 'face or floor 8 of the car. This table or brick supporting platform S)l is mounted or secured to fire resistingr side members l1 and an intermediate member l2 as is clearly shown in Figs. and 6. Depending from the sides of the ea' are continuous rails 13 and llt-which are lutcd in sand boxes as l5 secured to the side walls of the tunnel and which are designed to prevent the access of heat to the oar and thereby prevent injury or warping of the car. The passages or chambers formed between the vertically spaced platforms 8 and. 9 are loq,

. provided. with in rig. 5.

d'ampers as 16 which extend entirely' across the passages and are adapted for changing at will the direction of the heat either up or down through the cars during their passage through the kiln. (See Fig. 8.) These dampers may be operated by any suitable means, either by hand before car enters the kiln, or by means arranged within the kiln.

A plurality of furnaces as 17 are arranged adjacent the tunnels l and discharge their heat through passages 18 on the opposite sides of the tunnel being deflected upward by hre brick partitions 19 as shown clearly The heat so defiected passes to the top of the tunnel 1 and then downward through the brick 2O which is arranged on the platform 9 of the car, with spaces 21 between them as shown clearly in the various figures of the drawing, said brick being so arranged to permit the circulation of the heated air whereby it is brought into contact with the various bricks so arranged. The heat passing through the brick on the cars is deflected into the passage or chamber formed between the tables 8 and 9 by the action of a damper 22 arranged transverselyI across the tunnel 1 and which is adapted to be raised or lowered as desired. Arrows are shown in Fig. 1 illustrating of the heat current. When the damper 22 is raised a sufficient distance the heat passes from the chamber formed between the platforms of one car into thecorresponding chamber of an adjacent car and thence passes upward through the openings 10 in the platform 9 of said last mentioned car and through the brick mounted thereon to the flues 23 arranged above the opening through the top of the tunnel and which are provided with dampers as 24- for regulating the draft thereof. This tunnel 1 is provided at its opposite ends with doors 25 and 26 and when it is desired to introduce ai new `carload of brick into the kiln the doors 25 and 2G and the damper 22 are opened simultaneously and the car introduced through the opening 26 which forces the cars in front of it forward and discharges the car adjacent the door 25 into the transfer chamber 3 and the doors 25 and 26 and damper 2 are again immediately closed.

The transfer chamber 3 has a track 27 eX- tending longitudinally thereof and transversely across the ends of the tunnels 1 and 2 and a car 28 is designed to travel on this track 27 and is arranged to receive the car ejected through the door 25. When the car from the tunnel 1 has been forced onto the car 28, said car 28 with its load is moved longitudinally in the transfer chamber pref erably by a suitable puli exerted through an opening 29 at one end of the chamber 3. When the car 28 has been brought into posi tion' opposite the tunnel 2, a tool inserted i the.

the general direction through the opening 30 will force the car containing the brick from the transfer car 28 onto the tracks in the cooling chamber or tunnel 2. The insertion of the car at this end of the tunnel 2 forces a car out from the opposite end of the tunnel and the brick contained on the car so forced out is in,condition to be removed and carted to a suitable place of deposit. The tunnel 2 forms the cooling chamber or tunnel wherein the heated product is gradually cooled thereby preventing cracking or checking of the brick.

The tunnel 31 is arranged parallel with the cooling tunnel 2 and preferably adja- .cent thereto boing connected with. said tunnel 2 preferably near` its discharge end by means of a conduit 32 having a fan 33 arranged therein and which is designed to draw out the heated air which egrudes from the cooling bricks and force it into the tunnel 31 which contains carloads of green brick to be dried before burning. A flue 34 having a regulating damper 35 arranged at the opposite end of the tunnel 3,1 draws the heated air forced in from tunnel 2 byv fan 35 through the tunnel 31 to bring it in contact with the brick contained on the various cars arranged in the tunnel 31; and the heated air so drawn through tunnel 31 prodnces a drying effecton the green brick in tunnel 31 and prepares it for the burning tunnel 1. While the fan 38 is not in any way designed for a cooling element for the brick inl tunnel 2, yet it produces a draft through said tunnel and thereby assists in the cooling of the brick. t is of course understood that the brick is not continually passing through these tunnels but remains therein for a greater or less time as may berequired, gradually cooling in the tunnel 2 whereby checking of the surface is prevented. The brick cars in tunnel 31 may pass in either direction.

The tunnel 1 is provided in one or both of its sides with a plurality of openings 36 covered by any suitable transparent material and which are designed to enable the operator to inspect the brick during the burning process.

It will thus' be obvious that the various.

tunnels are kept continuously supplied with cars loaded with brick in the various steps of being burned, the cars at the inner end of the tunnel 1 having been subjected for the longest period to the heat in the kiln` and as the car from this end of the tunnel is transferred to the cooling tunnel 2, a car is ejected is removed from the tunnel 31 and introduced through the door 36 into the tunnel 1` and this `process may be continuously performed making substantially an endless chain.

F rom the foregoing description taken in connection with the accompanying drawings from said tunnel 2 and another car Ithe. construction and operation of the invention'vvillbe readily understood without requiringa more extended ex lanntion.

l Various changes in the term; proportion and theminor details of construction may ie resorted to without departing from the ,principle or sacrificing any',of the advantagesof the yinvention as defined in the appended claim.

l elnirn as 1n invention:

A brick kiln having a track-.extending vranged on the upper falce thereof, .and an vof heat passing therethrough. ,l

In testimony whereof 'heve hereunto set my hand in presence of twosubscribiug witnesses.
